, NEW YORK, ASSIGNOR TO TI-IE WHITIN MASSACHUSETTS, A CORPORATION i OF SKEWER-MOUNTING.

Application filed August 15, 1911, Serial No. 644,251. Renewed September 3, 1913.

To all @071 out it may concern:

Be it known that I, HARRY GRANT KIM- BALL, a citizen of the United States, residing at Bronxville, VVestchester county, New

York, have invented the Improvements in produced device, adapted to be safely and securely confined in a perforation of the metallic creel rail and providing in a single structure a step-bearing for an upper skewer and a top-holding bearing for a lower skewer, the latter bearing being specially adapted to support the skewer with the least friction.

In the drawings which illustrate the invention, Figure l is a vertical transverse section of a metallic spinning frame creel to which the invention is applicable; Fig. 2 a side elevation of the improved mounting therefor and its locking ring; Fig. 8 a vertical section of the same in place in the creel; and Fig. 4c is a top plan of the mounting.

In the two-story creel of Fig. 1, the creel rails 1 are adjustably supported on a series of uprights 2 above the main frame of the machine, and the roving bobbins 3 are set on the skewers 4: which are supported, top and bottom, by the rails so that they may revolve freely under the gentle pull of the roving unwinding from the bobbins. It will be understood that the roving drawn ofi from the bobbins from the supply for the spindles of the spinning machine, which do not appear in the drawing.

The improved mounting consists of a piece of hard material capable of taking a high polish or glaze, such as crockery, porcelain or other fictile material, and is'preferably molded in a single piece of substantially circular cross-section with a laterally projecting flange at or near one end thereof. The mounting is shown by itself in Fig. 2 and the flange thereof is marked 5, being formed in this instance at the extreme upper end of head of the piece or block. The upper surface of the piece or block is concaved or dished as shown at 6, and its lower portion is tubular with rounded edges, as indicated at 7 in Fig. 3. The margin of the head flange 5 is also beveled or rounded as shown in the drawings, and the whole is well glazed, especially on its upper surface 5 and the inte- Specification of Letters Patent. i

rior surface of the tubular part. The mounting as thus formed is adapted to be inserted in a perforation in the creel rail which is made slightly larger than the diameter of the porcelain so that contraction of the metal or expansion of the porcelain will not cause the latter to crack or break, and a locking means is applied to the mountingron the side of the rail opposite to the,

head flange so that the mounting will be confined in place in the rail by the flange on one side and the locking means on the other. The flange rests preferably on the upper margin of the perforation, forming the vertical support for the device and the locking means consists in the present instance of a split-ring 8 adapted to be snapped into an annular groove 9 formed on the porcelain piece just beneath the head flange, as shown by Fig. 3. When confined in this position, the base or foot P of an upper skewer is adapted to be stepped on the highly glazed, dished surface 6 and the top 4: of a lower skewer is adapted to be inserted in the depending tubular part 7, the two skewers being thus supported in substantial alinement with each other. The interior of the tubular part 4* is also highly glazed, as above stated, and forms a top-holder for the skewer which is superior to any means heretofore suggested for this purpose, since the friction of the tip of the skewer thereon is thereby reduced to a minimum and the bobbin willtherefore revolve uniformly under the slightest tension of the roving. Such rotation will tend to polish the wooden skewer tip rather than to wear it away as in the case of other top holders, and thus improve the action with continued use. If the frictional resistance to the rotation of the skewers is not constant the resulting variation in the tension of the roving will produce thin spots therein which will pass into the lit) pose'or I in place against accidental displacement,

such as indicated in Fig. 3, according as they are used in the top and bottom or the middle rails of the creel. Itwill be further observed that the improved mountings are easily placedv in and removedfrom the rails without requiring special tools for this pur-' depending on friction to retain them this latterfea-ture being of special importance inasmuch as in metallic creels any bearing made of vitreous material is likely to crack or burst under the frictional pressure. The positive confining means included as a part of this invention is therefore an important feature.

I claim:

1. A skewer mounting for metallic creels comprising a one-piece body or block of fictile material formed with a tubular lower portion adapted to receive a skewer tip and a dished uppersurface forming a step-bearing, and provided with a laterally disposed Copies of this patent may be obtained for five cents each, by addressing the 3. A skewer mounting for metallic spinning creels comprising a member adapted to be held in a perforation in the creel and having a laterally projecting supporting flange, a tubular part below'the flange adapted to receive the top of a lower skewer and an upper surface formed as a step-bearing for the base of an upper skewer.

4:. A skewer mounting for metallic creels composed of a block or piece of highly glazed, fictile material formed" with a tubular lower portion adapted to receive the tip of a skewer, and means which are not subject to expansile pressure against said piece for supporting the sameina'perforation in a metallic creel rail.

5. A skewer mounting for metallic creels composed of step-bearing surface, a topholding surface and a lateral flange surface,

all combined in a single structure and adapted to be placedin a perforation in the metallic creel rail, combined with non-frictional means for confining such structure within its said perforation, whereby'it is relieved of eXpansile pressure. 7

In testimony whereof, I have signed'this specification in the presence of two witnesses.
